An Prediction Market Trader Earned $436K on Wagers on Maduro's Downfall.

A trader earned a substantial sum from wagers on the downfall of Venezuela's president just before it was publicly declared, leading to inquiries about whether someone profited from inside knowledge of American actions.

Sudden Shift in Wagers

Predictions made on the forecasting site, a blockchain-based service, that the Venezuelan president would be no longer in control by the end of January surged in the time leading up to President Donald Trump declared on the weekend that the Venezuelan leader had been seized.

One account, which joined the platform recently and took four positions, all on the Venezuelan situation, earned over $nearly half a million from a modest bet of over $32,000.

Who placed the bet is a mystery. The anonymous account had only a blockchain identifier for identification.

Odds Fluctuate Before Public Statement

Market statistics shows that traders put the odds of a political change at just a low 6.5 percent in the midday period of the prior Friday.

Yet the odds had increased to over 10% by shortly before midnight and surged in the first hours of January 3rd, suggesting a sharp shift in market sentiment immediately prior to the official statement was made.

"This particular bet has all the hallmarks of a bet based on non-public details," said an industry expert.

A small number of other platform users also made tens of thousands of dollars from predicting the capture.

Regulatory Scrutiny Intensifies

Elected officials are beginning to pay attention.

A new rule put forward on the start of the week would prevent government employees from participating on prediction markets if they have "confidential government knowledge" related to a market.

Market Background

Forecasting platforms have become increasingly popular in the past few years, with participants able to predict everything from sports outcomes to politics.

This sector faced scrutiny under the last presidential term. But it has received a warmer welcome during the present political climate.

Insider trading is illegal in the securities markets, but there are less oversight in the prediction market arena.

An official representative for a competing service said their site "has clear rules against trading on insider information of any form."
